M37 open cluster in Auriga. Taken Nov 5, 2010 with 105mm A&M apo refractor at f/5 with Borg .85x flattener/reducer and Canon 5DMkII at ISO 800 for stack of 5 x 10 minute exposures, Mean combined. Used Celestron CGEM mount and SkyWatcher SynGuider on William Optics 66mm guidescope. All seemed to work well.

The complex area of clusters and nebulosity in central Auriga, including: M38 the Starfish Cluster and its smaller companion cluster NGC 1907; the emission/reflection nebulas NGC 1931, IC 417, IC 410 and IC 405 (from right to left here). Magenta and cyan (from emission and reflection components) IC 405 at right is the Flaming Star Nebula. Between IC 405 and IC 410 is the asterism known as The Little Fish. This is a stack of 8 x 7 minute exposures at ISO 800 with the modified Canon 6D on the TMB 92mm apo refractor at f/4.8 with the Borg 0.85x compressor flattener. The night was a little hazy. The field is turned slightly from being oriented with North up as is usual for me, to frame the area better. North is toward about 10 o'clock on this frame.
